Chinese babies, accompanied by their parents, take part in a baby swimming contest at a stadium in Beijing on Sept. 11, 2010. The organizer hopes to break the Guinness World Record for the most babies swimming together. China's government maintains that the one child policy has averted 400 million births since the strict policy was implemented in 1979. The government has vowed to enforce the policy until at least 2033, when the population is expected to peak at 1.5 billion.
